Satirical newspaper Frettirnar mocked that “Americans intended to give every Reykjavik citizen a paralysing drug during Pence’s visit”.

Helicopters hovered over the government building where Mr Pence met with Icelandic eland’s officials as snipers perched on neighbouring rooftops.

Ahead of Mr Pence’s arrival, three CV-22B Osprey flew over southwestern Iceland, along with two C-130 Hercules and one Lockheed C-5 Galaxy.
